   The failure is duplicated. Go to step 3.

   NO 

   If the HDS indicates PASSED, go to step 2. If the HDS indicates NOT COMPLETED, keep idling until a result comes on.

   Does the HDS indicate FAILED?

   YES 

   Go to step 3.

   NO 

   If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the CKP sensor and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot - Refer to: How to Troubleshoot the Fuel and Emissions Systems (2017) . If the HDS indicates NOT COMPLETED, retest and check the OBD STATUS again.

3. CKP sensor circuit connectors and terminals condition check

   -1. Check for poor connections or loose terminals at these locations:

   • CKP sensor
   • PCM
   • Engine ground
   • Body ground

   Are the connections and terminals OK?

   YES 

   Go to step 4.

   NO 

   Repair the connections or terminals.

4. CKP pulse plate visual check

   -1. Remove the CKP sensor, and check for damage to the CKP pulse plate.

   Is the pulse plate damaged or loose?

   YES 

   Replace the CKP pulse plate .
